At present, there are many short message calls from fake banks. The bank does invite high-quality customers to apply for cards by phone, but it won't tell you the specific amount. At most, they will tell you a general idea. The person who called you is in charge of credit card marketing, not the approver, so they can't determine your amount. Be careful not to reveal personal information on the phone. If necessary, you can call the CCB credit card customer service hotline to verify the authenticity. If you want to apply for a card, you can apply directly to any CCB nearby. Now you can apply for a card without going out. Log in to CCB official website to apply online.
